Description

tert-Butylxylenol CAS NO 36812-13-2 is a versatile alkylated phenol derivative valued for its antioxidant and stabilizing properties in various industrial formulations. This compound is essential for enhancing the shelf life and performance stability of sensitive materials by inhibiting oxidative degradation. It is a critical raw material for manufacturers in the polymer, lubricant, and specialty chemical industries seeking reliable additive solutions.

Application

• Primary antioxidant and stabilizer in polymer and plastic production (e.g., polyolefins, PVC).
• Additive in industrial lubricants and greases to prevent oxidation and extend service life.
• Intermediate in the synthesis of specialty chemicals, including other phenolic antioxidants and UV stabilizers.
• Stabilizing agent in fuels and hydrocarbon-based fluids to control gum formation.
• Used in the formulation of adhesives, sealants, and coatings to improve durability.
• Potential use as a preservative or antimicrobial agent in select industrial biocides.
